This is not far from the idea that we were kicking around for julia fractals and
isosurfaces one night. The idea is to create a "box" of six grids, containing sphere
sweeps, exactly the way height_fields are implemented in POVGUI, but completely
surrounding the object. Using trace, the points would be translated to the point
where they hit the object. Points that did not hit the object would be deleted. I
never tried this, so I don't know if it would work or not, but it is a way to derive
wireframes from irregular objects.
